Letters Patent No. `107,6 56, dated September 27, 1870.

IMPRovMN-i'- INv couPLlNe-JACKS.

The Schedule referred to in thegeLetters Patent andpxaking part of the sanne.

We,`HENRIIA. BROWN `and Err-Has' B, KEITH,

" both of Galesburg, inthe county of Kalamazoo and State of Michigan, `have inventedcertain Improvel ments in the Mode of Transmitting Motion to Shafts,

adjustable to any desired angle with the leading shaft, which invention we call`-A Universal Coupi lling-Jack, and'of which the following is a specifica-I,

tion. j j I I Our invention relates totheemployment ofa circular-recessed case or frame, (in which is sunk an inv termediate doilble-'coggedf'beyelwheel, one face of I `which gears with a pinion-shaft hung to said case,) in" combination with an adjustable ring-frame, 'carrying 1 `another shaft and pinion,Igea1iug withI the opposite "cogs of the intermediate wheel, said ring-frame being `adj ustably secured by `set-bolts within ay circular seat formed Iin said case in such manner thatthe one shaft may be adjusted radially iu the casing at any desired angle withl the other, vertically,l horizontally, or bot-h,

for portable or stationaryfuses.

I1`i,f,r urc 1 Iis a perspective view embodying our' inventionas mounted on a bed-frame. for portable uses; I l' I Figure 2 Iis va central Across-section, the`Itwo shafts "being shown `in a. line coincident with each other.

Similar letters of reference indicate corresponding parts in boihguree. I I

A is a circular or disk-like cast-iron case or frame, recessed centrally to receive the intermediate (bevelwheel B, cogged` ontwo faces, and carried on a shaft,

C, one journal only of saidshaft working in a bearing e formed in the c enteil of the `case, as at .1), the other journalworking in a bearing, bI',formed in the center of one or more arms, c, of a ring-frame', D, to be presently described. j I e I In' addition to the ce1 xtral.'recess for the intermediate wheel, au adjacentcircnlar rabbetcd seat is formed in the casing Aleavingan external rim, r,

j within which theriug-frame D' of cast-ironis snugly enclosed, or rather surrounded,Iwith `sufficientfreedom to permit its being revolved in its seat.`

lhe rngframe `is provided with two elevated bearings, a, on `its outer face, `in `which bearings a. shaft, E, (extending radially across the ceutel'y) revolves, and a similar, but shorter, shaft, F, revolves in similar bearings on the lower or outer face of thecase A.

Eachlof the shafts E and 11 carry a'matched Ibevelywheel .o1'?1)in ion,1,'to engage respectively with the geared faces .of the intermediate wheel B, n n opening being cut through the casing to admit a part of' thc body of the pinion on the shaft F. I

Either onev of said shafts may be thc driver, and the gearing may, ofcourse, be so proportioned as to driven from theintermediate. I The ringsframe, carrying with it the shaft EmayI e transmita slower, fasterl or equal motion to the shaft be `firmly secured to the case, in any desired position, i

by set-bolts i i., 85e., screwed through the rim against the edge of the ring, but in this way it is best to point bluntly the ends of the bolts, and have the bolts abut against a beveled edge, having a tendency to keep the 1ingf1'ame pressed firmly down to itsseat.

The jack, shown in f'ig.- 1, is mounted on framed bed-sills,` J, for staking down between a sweep horsepower and athrashing or other portable machine, the Itumblingrod ofthe power being jointed to the coup ling-fork f and the machine-connection to the fork f'. but for a belt used to drive the machine, the shaft E willof course be furnished with a band-wheel in place of the coupling.

Forthrashing or other Aportable uses, the machine will always be located in the most favorable vposition for its work, and that position will necessarily deterininc approximately t-he location of the jack, according to the nature of the connection.

Now, bythe use of our improved jack, the third point, viz.,.the position of the power, Iis not an ar bitrary one, as in theordinary arrangement, but may be selected to suit the ground at any-point within the `circmnference of a circle, the radiusot' which is equal to thelength of the tumbling-rodconnection.

Therefore, to adjust the" shaft E to coincide with the machine,`and the shaft l to coincide vwitlrthe power,- the ring-frame D is revolved'in its seat within the casc'A, until thc two shafts assume the proper `angle with cach other, when thcIconnectIons may be made, the power and jack staked down, andthe ring-frame secured in-place by tightening up the sete The utility of this universal adjustment may be readily selen when it is considered that portable sweep-powers can seldom be conveniently or suitably set downin a right line, or at a right angle with the machine to be driven'. V For'usc in shops, to transmit motion and power to shafts or belts, in any required direction, onr jackl may be mounted between hangers, or 1u any' suitable frame, adjustable or not, as the arrangement is strong,

i simple, and compact, and works'eqnallywell-in what ever position it may be placed.

le claim asv our invention-` v 'y A jack, ibi-,transmitting motion and power, conv posed of the gear-'shafts E F, intermediate wheel- B, circular case A, and adj ustablc ring-frame D, in combination withcach other, and any sui-table bed-sills,

or other frame, when arranged and operated substantially as and for the purpose set forth.
